SPECIFICATION forming part of Letters Patent No. 371,798, dated October 18 1887.

Application filed July 19, 1887. Serial No.'244,73l. rMvde.)

T0 aZZ whom, it may concern:

Be it known that l, AMOS STANDING,of Duquoin, in the county of Perry and'State of Illinois, have invented a new and Improved SealLock, of which the following is a full, clear, and exact description.

My invention relates to an improvement in seal-locks, and has for its object to provide a look whereby the car-door cannot be opened without detection, and wherein the construction of the lock will be simple and durable.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of thisspecificatiou, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of theloclgand Fig. 2 is a front elevation of the detached back plate. Fig. 3 is avertical longitudinal section on line 3 3 of Fig. 2, and Fig. 4 isa horizontal section on line 4 4 of Fig. 2.

The body of the lock is constructed of two, preferably rectangular, plates, 1 and 2, bolted together in any approved manner.

Both the front plate, 1, and rear plate, 2, are provided with a horizontal recess, Sand 4,near the lower end,upon the inner face, and to the right and above said horizontal recesses with registering circular recesses 5 and 6,' and to the left, above the horizontal recesses 3 and 4, in the edge of each plate, registering segmental recesses 7 are made, as shown in Figs. 1 and 2.

In the back plate, 2, above the circular recess 6, a perpendicular groove, 8, is cut, adapted to intersect said recess, and in said groove a spring-actuated pawl, 9, is made to slide, as shown in Fig. 2. The top of the plate 2 is provided wit-h upwardlyextending lugs 10, in which a cover, 11, is pivoted, adapted to project over the outer plate, for a purpose hereinafter set forth.

In the front plate, 1, below the center, a substantially-rect-angular aperture, 12, is provided, intersecting the circular recess 5, as shown in dotted lines, Fig. 1, and extending downward into the horizontally-recessed por- Within the registering circular apertures 5 and 6, when the two plates are bolted together, a disk, 15, is held to revolve, provided with a peripheral slot, 16, a central integral post, 17, and a horizontal rib, 18, integral with the disk, projecting from one side of the post 17, but to the periphery, as shown in Fig. 2.

Thepost 17 is adapted to project through the aperture extending from the recess 5 through the face projection 13, being provided outside the plate 1 with a horizontal pin, 19, whereby the disk is rotated, as illustrated in Figs. 1 and 3.

In the registering horizontal recesses 3 and 4 a bolt, 20, is held to slide freely, provided near one end, within the said recesses, with a deep longitudinal slot, 21, in the upper edge, as shown in Figs. 2 and 3, and in the same edge, nearer the end, a shallower and shorter slot, 22, is produced, which slot, when a seal is used, is adapted to be outside the plates. Below the slot 22, in the bolt 20, an aperture, 23, is made, as shown in Fig. 2. In the registering slots 7 the inner end of an angular arm, 24, is pivoted, the outer end be ing of a width to enter the slot 22 of the bolt and prevent the same from being slid out of the plates until the arm is lifted, a lip, 25, being provided in the outer edge for that purpose. Near the lower edge of the arm 24 an aperture, 26, is produced, aligning the aperture 23 when the bolt and arms are in contact, whereby the two may be fastened together by the usual lead seal when found desirable.

In connection with the seal-lock I employ a seal, 27, which may be of glass orother brittle and readily -broken material, which. seal is made slightly larger than the aperture 12,

which it is adapted to cover, and small enough to pass readily down the slot 14. The face of the seal, as illustrated, is adapted to have produced thereon the initials of the road, the sta- Lion-number, and the consecutive number of the seal, in order that the seal may not be counterfeited, as all the seals or plates are given a consecutive number,eommencing,for instance, at O.

In operation the plates 1 and 2 are bolted to the cardoor jambs, and the bolt 20 is fastened to the car-door in such manner as to readily enter the horizontal recesses 3 and 4 in the plates. The bolt having been entered in the combined plates, the seal 27 is entered in the slot 14 at the top and allowed to drop down, whereupon the face exposing the lettering will cover the aperture 12 and the lower end will enter the slot 21 and rest upon the bolt 20, as shown in Fig. 2. By means of the pin 19 the disk is now turned until the rib 18 strikes the top of seal 27, whereupon the springactuated pawl 9 will drop into the slot 16 of the disk and hold the same immovable from the outside. It is obvious that if an attempt is now made to draw the bolt the seal 27 will be broken thereby and the fact bemade apparent that an attempthas been made to open the car, as the bolt cannot be withdrawn at any time without injury to the said seal. When a new seal is to be inserted, the rib 18 may be carried out of the way by simply rotating the disk 15 to the left by turning the post 17.

It will be observed that the cover 11, folding over the goove 14, will preventrain, snow, sleet, or cinders entering the groove, and so let the seal 27 work freely in said slot.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a seal-lock, the combination, with the apertured front plate and a slotted sliding bolt, of a fragile seal fitting in the slot of the said bolt and a locking device engaging the upper edge of the seal and holding the same immovably,substantially as herein shown and described.

2. The combination, with a seal-lock provided with an aperture in the front seal and a fragile indicating-seal covering said aper- Lure, of a sliding bolt slotted to receive the lower end of.said fragile seal, a revoluble disk provided with a rib adapted to engage- .1, provided with the aperture 12 and slot 14,

the rear plate, 2, and the fragile indicatingseal 27, of the slotted bolt 20, the revoluble disk 15,provided with arib, 18, upon one face,

and a peripheral slot, 16, said rib adapted .to engage one upper edge of the breakable seal 27, and a spring-actuated pawl, 9, adapted to engage the said slot 16,substantially as shown and described, whereby the bolt cannot be withdrawn without breaking the seal 27, as set forth.

4. The combination, with the front and rear plates,1 and 2, provided with registering horizontal recesses 3 and 4,registering circular recesses 5 and 6, the vertical slot 8 in plate 2, adapted to intersect the recesses 6, a central vertical slot, 14,- in plate 1, and a fragile indicating-seal, 27, adapted to enter said slot 14 and cover an aperture in the front plate, of the slotted bolt 20, the revoluble disk 15 provided with the rib 18 and peripheral slot 16, said rib adapted to engage the seal 27,and a spring-actuated pawl, 9, adapted to enter the slot 16 of the disk 15, all arranged to operate substantially as herein set forth.

5. The combination, with the front and rear plates,1 and 2, provided with registering horizontal recesses 3 and 4, registering circular recesses 5 and 6, a vertical slot, 8, in plate 2,

adapted to intersect the recess 6, a central vertical slot, 14, in said plate 1, and a fragile indicating-seal, 27, adapted to enter said slot 14 and cover an aperture in the front plate, of a sliding bolt, 20, provided with slots 21 and 22 in'the upper edge, and an aperture, 23,below the slot 22, the revoluble disk 15, provided with a central post, 17, rib 18, and a peripheral slot, 16, aspring-actnated pawl, 9, adapted to engage the said slot 16, and a pivoted angle-arm provided with an aperture, 26, and adapted to enter the slot 22 of the bolt 20, all arranged to operate substantially as herein set forth.

6. The combination, with a longitudinally and transversely slotted casing provided with a front aperture aligning the longitudinal slot, of a bolt adapted to the transverse slot and provided with a recess aligning thelongitudinal slot of the casing, a revoluble disk provided with a radial rib and mounted in the casing to partly register with the longitudinal slot of said casing, means for revolving the disk, and a pawl engaging a notch in the disk, substantially as set forth.

7. The combination, with a longitudinally and transversely slotted casing, a bolt adapted to said transverse slot and provided with a recess and an aperture at its outer end, and means for locking a fragile seal in contact with the bolt, of an angular arm pivoted in the casing and provided with an aperture in its free end, substantially as set forth.
